Gigahertz optoacoustic vibration in Sub-5 nm tip-supported nano-optomechanical metasurface
Abstract
Nano-optomechanical systems plays an indispensable role in all-optical manipulation of light but high energy losses severely limit their development. Here the authors show ultrafast all-optical manipulation in a sub-5 nm tip-supported optomechanical metasurface.
